摘要

完成了一种应用于海上微小型浮标端天通一号卫星通信系统应用处理单元(AP)的设计与实现。AP单元不仅控制伺服单元实现恶劣海况下天线自动跟踪卫星信号波束,而且实现卫星通信系统快速接入天通一号卫星网络并进行数据传输的功能。模拟四级海况条件下的测试结果表明,浮标体横摇角在-30°～+30°范围内,AP单元驱动伺服单元实现卫星信号波束跟踪精度优于2°,通信系统在10 s内快速稳定接入卫星网络,能实现海上浮标和岸基站间1.2～384 kb/s码率的实时通信。

Abstract

An application processing unit (AP) for Tiantong satellite communication systems at the end of a small maritime buoy has been designed and implemented.The AP not only controls the servo unit to achieve automatic signal bean tracking of the antenna under adverse sea conditions,but also realizes the function of satellite communication systems to quickly access the satellite network and carry out data transmission.The simulated test under four levels of sea conditions shows that the buoy transverse swing angle is in the range of -30° to +30°,and the AP unit drives the servo unit to achieve the satellite signal beam tracking accuracy better than 2°,and the terminal is quickly and stably connected to the satellite network within 10 s,realizes the data communication between the buoy end of the sea and the shore base at the code rate of 1.2~384 kb/s.
